Technical indicators

1. Measuring parameters: temperature, PH, ORP, conductivity, TDS, salinity, dissolved oxygen, residual chlorine, ozone, turbidity, suspended solids, sludge concentration, hardness and some ions.

Generally, a multi parameter instrument can only select 5 parameters at most. For example, the combination mode of some conventional parameters:

① Temperature PH, conductivity, dissolved oxygen, residual chlorine

② Temperature PH, ORP, residual chlorine, turbidity

③ Temperature PH, TDS, dissolved oxygen, sludge concentration

④ Temperature PH hardness dissolved oxygen turbidity

If six parameters are specially required, the general combination mode is:

★ Temperature, PH, conductivity, dissolved oxygen, residual chlorine and turbidity.

★ Temperature compensation: 0-60 ℃

2. Working conditions: ambient temperature 0-60 ℃, relative humidity ≤ 90%

3. Communication mode: 4-20MA (one channel by default, two channels need to be specially customized); RS485 (one channel by default, two channels need to be specially customized)

4. Output load: load ＜ 750 Ω (4-20mA)

5. Working voltage: 220VAC 10%, 50/60Hz or order DC24V and DC12V power supply

6. Size: 590 * 390 * 1500mm

7. Installation mode: movable cabinet type

8. Weight: 80KG

9. Protection grade: IP65, waterproof, moisture-proof and dust-proof.
